Full textAbstract:
John Calvin holds that the fall radically changed humanity’s moral and epistemic capacities. Recognizing that should lead Christian philosophers to see that philosophical questions require at least two sets of answers: one reflecting our nature and capacities before the fall, and the other reflecting our nature and capacities after the fall. Our prelapsarian knowledge of God, the right, and the good is direct and noninferential; our postlapsarian knowledge of them is mostly indirect, inferential, and filled with moral and epistemic risk. Only revelation can move us beyond fragmentary and indeterminate moral and theological knowledge.

This article delves into the origins of the first national multi-sector employers' associations in Denmark and the United Kingdom to understand why some countries produce highly-centralized, unitary national business associations, which develop labor market coordination with unions and the state. In contrast, other countries conclude their experiment with coordination by ultimately falling back on laissez-faire liberalism. In particular, I explore how the structure of party competition works to augment or to diminish coordination among employers. I argue that the interplay of party politics in the policy-making process influenced the incentives of opposing parties to block the legislation sought by employers, informed the incentives of the business-oriented right parties to delegate policy-making authority to private business and labor organizations, and shaped the capacities of employers to get what they wanted from the state.

Full textAbstract:
Communities in which species are obligately associated with a single host are ideal to test adaptive responses of community traits to host-imposed selection because such communities are often highly insulated. Fig species provide oviposition resources to co-evolved fig-wasp communities. Dispersing fig-wasp communities move from one host plant to another for oviposition. We compared the spatial dispersion of two fig species and the dispersal capacities of their multitrophic wasp communities. Dispersal capacities were assessed by measuring vital dispersal correlates, namely tethered flight durations, somatic lipid contents and resting metabolic rates. We suggest that dispersal-trait distributions of congeneric wasp species across the communities are an adaptive response to host plant dispersion. Larger dispersal capacities of the entire multitrophic community are related to more widely dispersed resources. Our results provide evidence and a novel perspective for understanding the potential role of adaptation in whole-community dispersal-trait distributions.

Full textAbstract:
The early adolescent’s state of mind in the Adult Attachment Interview (AAI) is more closely linked to social interactions with peers, who are unlikely to serve as attachment figures, than it is to (i) qualities of the adolescent’s interactions with parents, (ii) the AAI of the adolescent’s mother, or (iii) the adolescent’s prior Strange Situation behavior. This unexpected finding suggests the value of reconceptualizing AAI autonomy/ security as a marker of the adolescent’s capacity for emotion regulation in social interactions. Supporting this, we note that the AAI was originally validated not as a marker of attachment experiences or expectations with one’s caregivers, but as a predictor of caregiving capacity sufficient to produce secure offspring. As such, the AAI may be fruitfully viewed as primarily assessing social emotion regulation capacities that support both strong caregiving skills and strong skills relating with peers.

"Computer simulations show that Neanderthal facial morphology represents adaptation to cold and high energy demands, but not heavy biting."

Full textAbstract:
Three adaptive hypotheses have been forwarded to explain the distinctive Neanderthal face: (i) an improved ability to accommodate high anterior bite forces, (ii) more effective conditioning of cold and/or dry air and, (iii) adaptation to facilitate greater ventilatory demands. We test these hypotheses using three-dimensional models of Neanderthals, modern humans, and a close outgroup ( Homo heidelbergensis ), applying finite-element analysis (FEA) and computational fluid dynamics (CFD). This is the most comprehensive application of either approach applied to date and the first to include both. FEA reveals few differences between H. heidelbergensis , modern humans, and Neanderthals in their capacities to sustain high anterior tooth loadings. CFD shows that the nasal cavities of Neanderthals and especially modern humans condition air more efficiently than does that of H. heidelbergensis , suggesting that both evolved to better withstand cold and/or dry climates than less derived Homo . We further find that Neanderthals could move considerably more air through the nasal pathway than could H. heidelbergensis or modern humans, consistent with the propositions that, relative to our outgroup Homo , Neanderthal facial morphology evolved to reflect improved capacities to better condition cold, dry air, and, to move greater air volumes in response to higher energetic requirements.

AbstractUniversal Grammar promotes the study of an idealization of language behavior and language learning. In examining the diversity of actual behavioral strategies used to achieve linguistic goals, Evans & Levinson (E&L) move towards studying language as a behavior. This approach can benefit from studying communicative and cognitive capacities more broadly – across species. We exhort like-minded linguists to cast off the remaining intellectual shackles of linguistic speciesism.

Writing analytics has emerged as a sub-field of learning analytics, with applications including the provision of formative feedback to students in developing their writing capacities. Rhetorical markers in writing have become a key feature in this feedback, with a number of tools being developed across research and teaching contexts. However, there is no shared corpus of texts annotated by these tools, nor is it clear how the tool annotations compare. Thus, resources are scarce for comparing tools for both tool development and pedagogic purposes. In this paper, we conduct such a comparison and introduce a sample corpus of texts representative of the particular genres, a subset of which has been annotated using three rhetorical analysis tools (one of which has two versions). This paper aims to provide both a description of the tools and a shared dataset in order to support extensions of existing analyses and tool design in support of writing skill development. We intend the description of these tools, which share a focus on rhetorical structures, alongside the corpus, to be a preliminary step to enable further research, with regard to both tool development and tool interaction

Full textAbstract:
This article analyses pay determination as a process of commensuration as well as a process in which commensuration can fail. The analysis is based on an empirical study of two collective firms in Germany and the United Kingdom and their attempts to self-determine fair pay. Due to the formal equality of members and their democratic decision-making processes, these cases are a specifically interesting context for studying the determination of pay. Through the analysis of a failed attempt at finding a formula for fair pay, as well as a fragile compromise formula, a contribution is made to the literature on commensuration and the construction of compromises. The article also extends this literature by explaining the obstacles to the creation of a compromise that would go beyond the need for a common interest. Callon and Muniesa’s work on calculation is used to clarify the steps that are necessary to move from questions of worth to the assessment of worth and its expression in measures. To introduce the question of legitimacy in evaluation processes, Callon and Muniesa’s framework is supplemented with Boltanski and Thévenot’s work on critical capacities.

Both of pesticides were adsorped using zeolites with batch method. Three difference types of zeolite were used for comparison. Those pesticides consisted of various Si/Al ratio which were 3.61 (Y), 8.61 (Y-10) and 111.35 (Y-100). The organo-zeolite, which modified with hexadecyltrimethyl ammonium (HDTMA) surfactant were used for comparison. It was found that the adsorption capacity of linuron more than atrazine 30 % for Y , 40 % for Y-10 and 10 % for Y-100. It can be explaned that the small molecules of linuron (thickness 6.12 Ao) could move onto pore size of zeolite (7.4 Ao). While the larger molecules of atrazine (thickness 9.6 Ao) could not do this. The maximum asorption capacities of all pesticides are Y-100 and MY-100 because they have most external area and hydrophobic properties which were form their most dealuminative potential. The comparison of MY-10 and Y-10 found that MY-10 has more adsorption capacities than Y-10 as follow 4 % for linuron and 20 % for atrazine since MY-10 has more increased hydrophobic force. Adsorption capacity of MY-100 is similar to Y-100. Adsorption capacities of MY is lower than Y since it has steric effect and pore blocked with surfactant. This results were identified by XRF, XRD, FT-IR, TGA and CHNS.

Full textAbstract:
A. M. Turing argued that there was "little point in trying to make a 'thinking machine' more human by dressing it up in ... artificial flesh." We should, instead, draw "a fairly sharp line between the physical and the intellectual capacities of a man." For over fifty years, drawing this line has meant disregarding the role flesh plays in our intellectual capacities. Correspondingly, intelligence has been defined in terms of the algorithms that both men and machines can perform. I would like to raise some doubts about this paradigm in artificial intelligence research. Intelligence, I believe, does not just involve the working of algorithms. It is founded on flesh's ability to move itself, to feel itself, and to engage in the body projects that accompanied our learning a language. This implies that to copy intelligence -- i.e., to produce an artificial version of it -- the flesh that forms its basis must also be reproduced.

Full textAbstract:
Cette thèse de doctorat mène une réflexion sur les mobilités juvéniles périurbaines sous l’angle de « l’entre-deux », terme caractérisant à la fois les espaces périurbains et la jeunesse. Comment la jeunesse vit-elle une localisation résidentielle, choisie par les parents, et se déplace-t-elle dans ces espaces peu densément peuplés et faiblement desservis par des transports en commun ? Quel rôle jouent les contextes périurbains dans la construction identitaire des jeunes ? L’étude menée, à partir de trois lycées généraux et technologiques situés dans les franges de l’agglomération parisienne en proie à un mouvement de périurbanisation plus ou moins ancien, a consisté à interroger une population lycéenne périurbaine par le biais de méthodes qualitatives (85 entretiens) et quantitatives (1522 sondés en ligne). Développant un ancrage différencié à l’espace habité dans lequel la maison individuelle tient une place centrale, les jeunes adoptent une multitude de stratégies pour s’émanciper des contextes périurbains. Ils combinent les ressources des entre-deux pour s’affirmer en tant qu’individu, y compris dans le cadre de la socialisation secondaire marquant cet âge. Ils y trouvent ainsi leur bonheur, bien qu’ils cherchent souvent, de manière plus ou moins réaliste ou réalisable, à sortir de ces espaces. Ces bricolages spatiaux les amènent à développer une motilité (Kaufmann, 2002) plus importante que celle des jeunes urbains. En revanche, à l’heure de s’inventer une vie adulte, ce n’est pas tant l’espace périurbain qui apparaît comme un obstacle à leur projet que les ressources sociales, financières ou culturelles de leur famille. Malgré tout, les contextes périurbains, parce qu’ils font territoires, sont des lieux où les jeunes projettent volontiers leur vie future, même si, pour certains, l’attraction urbaine ou de l’étranger est plus forteThe ‘‘space-in-between’’ refers to any specified situation or space characterizing an intermediary and transitional state. This paper aims at exploring the notion of “space-in-between” through the themes of mobility and the youth living in the periurban fringes of the Great Paris. How does the youth live the residential choice of theirs parents and move to those median zone between rural and urban areas where public transit is deficient? What role have the periurban fringes in the building of the youth identity? Across this research, led in three public high schools located in the periurban fringes of the Great Paris, 85 young spoke about their mobilities and 1522 answered a questionnaire. Become oneself ask to move alone, to explore new spaces without parents but with peers, so these young people combine a lot of means to leave these spaces (walking, hitch-hiking, car-sharing, taking school buses for shopping and so on). Developing a specific link with the periurban areas where the home could be perceived as a special place, these young people live happily and do not consider themselves as ‘‘prisoners’’ in their territories. Nevertheless, they try to going out of them: going to parties, meeting other young people in the night clubs, meeting their friends as they want, practising sport and cultural leisures, and moving anywhere without asking their parents to drive them. At the time to become an adult, when they want to follow high education currucula, if they don’t choose the same way that urban and rural students, it seems that financial ressources and capacities to move are central in their choice. Some of them want to live in big cities or in foreign countries but most of them imagine them living the perurban edges where they had grow up. So the periurban fringes seem, as territories, the ‘place to be’!
El « espacio de transición » es una situación o un espacio que se caracteriza por ser intermedio.Aquella idea de intermedio interesa a los geografos en sus investigaciones sobre el espacio periurbano. Este proyecto , como continuidad de un precedente trabajo de investigaciones (Ser joven en el periurbano de SENS. ¿ Qué movilidades para los alumnos del instituto JANOT ? ; Catherine DIDIER-FEVRE, Máster 2 investigaciones, 2011. 229 páginas), intenta explorar la noción de « transición » a través de las movilidades. Si el término periurbano se define por un espacio de transición (noción aparecida con la instalación de la población en una extensión de la zona urbana) entre dos contrapuestos : espacio urbano y espacio rural, el de la juventud responde también a la noción de « espacio de transición ». En efecto, la juventud es la transición entre la desaparición de las claves de la infancia y la construcción de nuevos modelos. Es un tiempo de experiencias.Mientras « el periurbano sigue siendo el espacio de la juventud en una sociedad envejeciéndose : es el único espacio donde encontramos más de 3 jóvenes para con 2 mayores», muy pocas cosas fueron escritas sobre la juventud del periurbano. Aquella idea de las movilidades de la juventud es nueva. Tener en cuenta la edad de los habitantes de un espacio definido es fundamental para entender las relaciones de ellos con su territorio. Hasta ahora sólo los mayores o los niños pequeños preocuparon a los geografos del periurbano. Al investigar sobre los jóvenes del periurbano una se pregunta :¿Qué relaciones viven los jóvenes con el territorio periurbano al vivir una movilidad singular ?

Full textAbstract:
The procurement of agricultural commodities by multinational organizations has been identified as a leverage point for moving the global agricultural system towards sustainability. This study focuses on how multinational organizations can improve their capacities to procure more sustainably grown agriculture commodities. Using the Framework for Strategic Sustainable Development (FSSD) to create a theoretical ‘Ideal Case’ for procurement practices, this study analyzes the key strengths and weaknesses of existing practices surrounding the procurement of agricultural commodities in order to determine how they can improve. Interviews with four multinational corporations, one INGO and several experts in the field showed various weaknesses, including a lack of whole-system perspectives, inadequate definitions of sustainability, and weak strategies and tools to support organizations’ movements towards sustainability. Using these findings, recommendations were created to provide procurers, sourcing managers, supply chain managers, and sustainability managers with the necessary guidance to create conditions enabling the procurement of more sustainably grown agricultural commodities. The recommendations call for multi-stakeholder cooperation, increased use of impact assessments, long-term sustainability goals, and credible certification systems.

You, Wei. "Exploring multiple-mode vibrations of capacitive micromachined ultrasonic transducers (CMUTs)." Thesis, University of British Columbia, 2013. http://hdl.handle.net/2429/44222.
Full textAbstract:
Capacitive Micromachined Ultrasonic Transducers (CMUTs) are considered advantageous over piezoelectric transducers for ultrasound imaging for the high bandwidth, ease of integration with electronics and miniaturization. Research efforts over the past two decades have been focusing on manufacturing and system integration of CMUTs to achieve comparable and better performance than the piezoelectric counterparts, while the uniqueness of the CMUT structure and physics is barely exploited.
This thesis explores the complex behavior of CMUTs from a mode superposition perspective, and demonstrates imaging applications using CMUTs' multi-modal operation. The operation of CMUTs is first analytically modeled as a coupled electro-mechano-acoustical system using plate vibration theory. As the simplest case, the first symmetric and asymmetric modes of vibration can be excited simultaneously via asymmetric electrostatic actuation, resulting in a vibration profile with a shifted center. Finite element modeling (FEM) is used to verify the theoretical calculation, and an equivalent circuit consisting of two sub-circuits for the symmetric and asymmetric vibration modes is built to show the possibility of fast simulation of complex CMUT array behavior. Experimental characterization of fabricated CMUT chips show that asymmetric vibration can be achieved with multi-electrode CMUTs.
Two imaging applications using the multi-modal operation of CMUTs are proposed. The first concept, tiltable transducers, explores the benefits of orienting each transducer element toward the focal point to concentrate the acoustic energy and reduce grating lobes and side lobes. Imaging simulation shows the grating lobes can be reduced by 20dB while the main lobe energy is preserved. FEM simulation demonstrates that CMUTs capable of asymmetric vibration can be a viable candidate as tiltable transducers with careful design of the cell dimension and central frequency.
The second imaging application takes advantage of the ringing response of a CMUT to off-axis acoustic sources to achieve super-resolution imaging with low computational cost. The differential responses across all CMUT cells form a more decorrelated pattern than the regular average responses, which leads to better estimation performance of the proposed super-resolution algorithm.
While only preliminary experimental results for the proposed applications are presented, the multi-modal operation concept shows potential in improving several aspects of ultrasound imaging.

De nombreux travaux de recherche ont ´et´e conduits dans le domaine de synthèse de lois de commande par modes glissants. Différentes approches de commande été proposées dans la litérature, telles que l’algorithme Super-Twisting (STA) et sa version récente, l’algorithme généralisé Super-Twisting (GSTA). Les travaux de recherche présentés dans ce mémoire de thèse s’inscriventdans ces méthodes pour résoudre le problème de commande et de commande tolérante aux fautes, pour une mission spatiale. La mission considère une cible passive et un chasseur. L’objectif visé est de synthétiser les lois de contrôle d’attitude et de mouvement relatif, tolérantes aux pannes. Les approches proposées abordent la problématique des modes flexibles des panneaux solaires etdes phénomènes de ballottement du carburant dans les réservoirs.Dans un premier travail, une loi de commande de type STA est proposée dans une configuration dite de backstepping. Dans un second travail, une loi de commande tolérante aux fautes basée sur les modes glissants du second ordre, est proposée. La solution est basée sur l’algorithme GSTA ,placé en boucle externe de compensation de défauts utilisant un estimateur de défauts non linéaire. Le problème de saturation des actionneurs est également abordé et une solution basée sur la géométrie polytopique, est proposée. Les éléments clés de l’approche tolérante aux pannes sont, i) d’une part la solution ne nécessite pas de diagnostiquer les fautes et donc n’utilise pas d’algorithme de détection et de localisation de défauts, et ii), d’autre part, l’approche est basée sur le formalisme duquaternion dual qui permet de tenir compte des effets de couplage attitude/mouvement relatif. Des critères orientés mission, illustrent les résultats obtenus au travers d’une campagne de simulation réalisteIncreasing attention has grown with regards to Sliding Mode Controllers (SMC). In order to reduce the so-called chattering effect, the Super-Twisting Algorithm (STA) has been proposed, recently. In this work, a controller based on the STA in a backstepping setup, is proposed for spacecraft rendezvous in a circular orbit. A key feature is that the chaser is not treated as a point mass, given that the effects of the flexible modes and propellant sloshing phenomena are considered. The results obtained are taken further, given that the guarantee of robustness against perturbations is not enough when it comes to critical systems, through the second ordersliding mode controllers technique. It is shown that the technique enables to solve to problem of fault tolerant control. The solution is based on the Generalized Super-Twisting Algorithm (GSTA) with an anti-windup strategy and a nonlinear observer and the dual quaternion formalism. The main reason of employing a GSTA is because it offers more robustness against state dependentperturbations (sloshing phenomena and flexible modes) than the STA. In addition, with the help of the anti-windup strategy, the control law does not saturate the thrusters, avoiding instablity when faults occur. The proposed solution is evaluated through a simulation campaign in a high-fidelity non-linear simulator, and mission oriented criteria demonstrate its potential

Full textAbstract:
Various types of current mode control are being used in different applications. Model for current mode control is indispensable for proper system design. Since 1980s, modeling of current mode control has been a hot topic in power electronics field. In current mode control, sub-harmonic oscillation is a common issue, especially for constant frequency current mode control: like peak current mode control, valley current mode control, or average current mode control.
Recently V2 control is becoming more and more popular due to its simple implementation ad super fast transient response. V2 control can also run into sub-harmonic oscillation just as current mode control. Efforts have been devoted to modeling of V2 control.
A common property of different types of current mode control and V2 control is that they are all multi-loop structures and the inner loops are all highly nonlinear. Due to the nonlinearity of the inner loops, modeling of these structures is extremely difficult. Up to now, there are two main problems which havenâ t been solved: 1. modeling of average current mode control; 2. modeling of V2 control with composite capacitors.
This thesis tries to solve these two problems and starts with V2 control. For V2 control with single type of bulk capacitors, an accurate model has been proposed previously. In this thesis, an equivalent circuit model is proposed to get better physical understanding. This method makes use of previous current mode control modeling result and relates V2 control with current mode control.
To model V2 control with composite capacitors, capacitor currents and output voltage time domain waveforms are analyzed. Based on describing function method, transfer function from control to output is derived. The modeling result shows that with more parallel ceramic capacitors, system has smaller stability margin.
For average current mode control, the structure is compared with V2 control. Similarity between the structures of current compensator in average current mode and output capacitor network in V2 control is identified. V2 model is utilized for average current mode control. The modeling derivation process is simplified. For the current compensator in average current mode control, it is not desired to have a high frequency pole from stability point of view.
As a conclusion, a circuit model for V2 control with bulk capacitors is proposed and another two problems are examined: modeling of V2 control with composite capacitors and modeling of average current mode control. It has been demonstrated that there is similarity between these two structures. The modeling results are verified through simulation and experiments.Master of Science

Full textAbstract:
Due to the recent rapid growth in personal mobile communication devices (smartphones, PDA's, tablets, etc.), the wireless market is always looking for new ways to further miniaturize the RF front-ends while reducing the cost and power consumption. For many years, wireless transceivers and subsystems have been relying on high quality factor (Q) passives (e.g., quartz crystal, ceramics) to implement oscillators, filters, and other key RF front-end circuitry elements. However, these off-chip discrete components occupy large chip area and require power-demanding interfacing circuits. As a result, a great deal of research effort has been devoted to the development of micromechanical resonators that are much more amenable to direct integration with integrated circuit (IC).
Over the past few years, vibrating RF MEMS (Micro-Electrical-Mechanical-System) resonator technology has emerged as a viable solution, most notably, the film bulk acoustic resonator (FBAR) and surface acoustic wave (SAW) resonator, which have already been successfully implemented into commercial products. Undoubtedly, micromechanical resonators such as FBAR's can perform as well as if not better than its bulky conventional counterparts and facilitate the miniaturization and power reduction of conventional RF systems. However, in some cases when multi-frequency functionality on a single-chip is needed, FBAR simply won't deliver.
To address this dilemma, contour-mode MEMS resonators have been developed and regarded as the most viable on-chip high-Q alternative. Unlike FBAR, contour-mode resonators use lateral dimensions to define its resonating frequencies, thus allowing for single-chip multi-frequency functionality. However, there is still room for improvement with respect to lowering the motional resistance of these devices to allow matching to 50 Ω electronics, while retaining low power consumption, small size, and simpler manufacturing process.
This dissertation presents the design, fabrication, characterization and experimental analysis of two types of micro-mechanical resonators. Piezoelectrically- and electrostatically-transduced micromechanical resonators will both be shown. Both types of resonator will be fabricated in the same micro-fabrication run, which makes the comparison between the two much more impartial. The impacts of substrate's resistivity over the device performances will also be studied.
Among the most significant results, this dissertation also presents several ideas that are enabled by the use of silicon-on-insulator (SOI) wafer. A novel single-mask fabrication process that can produce capacitive resonator with nano-meter gap is demonstrated. The concept of dual-transduced micro-mechanical resonator is introduced by combining both piezoelectric and capacitive based resonators. Finally, frequency tuning of MEMS resonator are explored and detailed in this work as well.

Ces travaux portent sur le développement d'un capteur capacitif de pluie à électrodes protégées fonctionnant en mode différentiel. Dans un premier temps, les propriétés électriques des différents matériaux constitutifs du capteur sont déterminées expérimentalement. A partir de considérations théoriques, nous avons établi des expressions semi-empiriques traduisant la dépendance en fréquence [10^2 à 10^5Hz] et en température [−40 à +80°C] des permittivités diélectriques, nécessaires aux calculs des capacités. Le capteur est ensuite dimensionné par simulation numérique (méthode des éléments finis) puis fabriqué selon différents procédés de dépôt pour les électrodes. Deux motifs d'électrodes sont étudiés : électrodes linéaires et électrodes interdigitées. La sensibilité à l'eau est évaluée par simulation numérique (film puis gouttes d'eau de volume variable) avant validation expérimentale. L'influence de la température sur les performances du capteur est finalement abordée : les effets de la dilatation thermique des matériaux et de la variation des permittivités diélectriques sont successivement traités. A l'issue de cette étude, l'efficacité du mode différentiel contre l'influence de la température est évaluée.

What we see is, say, a pig, or its perambulations, or its rooting beneath that oak. Sight offers us a certain form of awareness of this, characterized in one way by its objects. It thus offers us occasion for another sort: we may recognize what we are aware of as, for example, a case of a pig rooting, or of an interminable drum machine. We take up the offer in exercising capacities for recognition such as they are. John McDowell has argued that this cannot be quite right (or anyway complete). For it needs to posit rational relations where there can be none. What follows argues that McDowell cannot be quite right: if he were, thought would cease to exist.

Many emerging adults find themselves navigating the complex transition from adolescence to adulthood while enrolled in college. The key to navigating the demands of college (and emerging adulthood) is not simply what decisions one makes but also how one makes them. This chapter foregrounds college student development research regarding the developmental capacities that underlie young adults’ decision-making processes. Drawing upon two longitudinal studies of college student and young adult development, the authors show how young adults move from uncritically following external formulas learned in childhood toward gaining the capacity for self-authorship—a journey that involves developing internal criteria for crafting one’s identities, relationships, and beliefs and yields the ability to navigate external demands. The authors emphasize that diverse combinations of personal characteristics, experiences, and meaning-making capacities yield diverse pathways toward self-authorship. They also highlight how higher education can promote self-authorship and explore further research to better understand self-authorship’s relevance across cultures.

This chapter explains why love and care can be reliable capacities. Without love, or care, as a basic affective disposition, we would not have access to those features of the world that attract our attention and that move us to respond emotionally. That we are loving or caring beings structures how the world seems to us: what seems real and significant, what appears to be possible, as well as what arouses our attention and moves us to respond. A person who loves or cares minimally apprehends less and inhabits a diminished world. What it means to love someone or something is to value her or its life and well-being as an end in itself. Our heightened awareness of what we love and care about enables us to appreciate aspects of our surroundings that would otherwise have been lost on us: these emotional dispositions thus reveal meaningful features of the world.

This chapter turns on the concept ofsensationto sketch some of the ways plants are caught up in contemporary biopolitics. Specifically, the idea of the floral sensation both describes the spectacular qualities of (some) plants that make them particularly desirable commodities in the global floral industry, and gestures to recent research that indicate that plantshavesensations that are both similar to and radically different from human ones. Together, these meanings demonstrate that plants are extensively implicated in biopolitical relations, but as agents with specific capacities rather than as passive objects of manipulation. To understand the involvement of active plants in biopolitics, then, requires attentiveness both to the multiplicity of vegetal involvements in socio-political entanglements, and to the ways in which plants complicate questions of life itself; ethical and political responses to plant life must therefore move beyond assertions of plant similarity in the direction of also recognizing their unassimilable differences.

Full textAbstract:
Material Transgressions reveals how Romantic-era authors think outside of historical and theoretical ideologies that reiterate notions of sexed bodies, embodied subjectivities, isolated things, or stable texts. Essays examine how these writers rethink materiality, especially the subject-object relationship, in order to challenge the tenets of Enlightenment and the culture of sensibility that privileged the hegemony of the speaking and feeling lyric subject and to undo supposedly invariable matter, and representations of it, that limited their writing, agency, knowledge, and even being. In this volume, the idea of transgression serves as a flexible and capacious discursive and material movement that braids together fluid forms of affect, embodiment, and textuality. They offer alternative understandings of materiality that move beyond concepts that fix gendered bodies and intellectual capacities, whether human or textual, idea or thing. They enact processes—assemblages, ghost dances, pack mentality, reiterative writing, shapeshifting, multi-voiced choric oralities—that redefine restrictive structures in order to craft alternative modes of being in the world that can help us to reimagine materiality both in the Romantic period and now. Such dynamism not only reveals a new materialist imaginary for Romanticism but also unveils textualities, affects, figurations, and linguistic movements that alter new materialism’s often strictly ontological approach.

Full textAbstract:
This chapter argues that human beings are neither better (because of our moral nature) nor better off (because of our higher capacities) than the other animals. Our moral nature does not make us better because moral standards do not apply to animal action. Our higher capacities do not make us better off because the good of a creature is relative to the creature’s capacities. The two views share a common error. One thing can be better or better off than another only as measured by a standard common to both, not because different standards apply to them. The chapter also offers an explanation of the common intuition that death and certain harms are worse for more cognitively and emotionally sophisticated animals than for cognitively and emotionally simpler ones. While the explanation supports the intuition, doubts are raised about whether death is really less bad for some creatures than others.

This chapter assesses the capacities for a green growth transition in the United States. Although a leader in the early days of modern environmentalism, evaluations of US ecological policy and performance have been less favorable more recently. Whether or not this will change and the United States will embrace green growth depends on structural and political factors. The first describes relatively fixed institutional characteristics such as federalism, electoral rules, and economic composition. The second, political factors, are less fixed in the near term: the balance of political power, public opinion, and interest group activity. This analysis of capacities for green growth is used to propose a political strategy for change in the concluding chapter.

Full textAbstract:
Chapter 9 presents the idea that Literalism undermines current social and moral boundaries for moral status. Possession of psychological capacities, moral standing, and respectful treatment are a standard package deal. So either many more beings enjoy moral status than we now think, or the relative superiority of human moral status over other beings is diminished. It introduces the role of psychological ascriptions in drawing social and moral boundaries by examining dehumanization and anthropomorphism. It argues that in the short term Literalism does not motivate us to do more than make minor adjustments to current moral boundaries. We can distinguish the kinds of psychological capacities that matter for moral status from the kinds that best divide nature at its joints. In the long run, however, Literalism prompts us to reconsider the anthropocentric standards that govern current moral boundaries.

Full textAbstract:
Collisions of birds with human artefacts (power lines, wind turbines, glass sheets, etc.) are major source of bird mortality. Many birds are also killed by entrapment in fishing nets. A sensory ecology perspective on this problem shows that collision and entrapment occur because these hazards present perceptual tasks that are beyond the capacities of the birds; birds are carrying out tasks where a hazard would not be predicted; or birds perceive the hazard but make an inappropriate categorical response. Birds that fly into power lines and turbines may be simply not looking ahead or are flying in conditions in which their resolution is very low. Reducing collisions requires far more than attempting to make hazards more conspicuous to humans. It requires recognition of the birds’ perceptual limitations and their distraction away from hazard sites. This requires taking account of the particular ecological requirements and sensory capacities of each target species.

Teresa of Ávila is often cited in Anglo-American philosophical discussions of the epistemic significance of mysticism. Until recently, however, these typically involved quoting her selectively to bolster some particular view regarding which unusual transitory experiences count as truly ‘mystical’, whether they are ‘the same everywhere’, and what support they might provide for belief in God. This chapter suggests a broader approach that recognizes Teresa’s potential contribution to many other topics related to theological epistemology, including: the epistemic benefits of the ‘Teresian’ virtues; mystical growth as involving a fundamental transformation of one’s epistemic capacities; and mysticism as a complementary mode of knowing ‘through experience’ the same divine realities approached more indirectly by theological study.

AbstractResearch on the learning organization has, so far, failed to appreciate the relevance of two intertwined loci of learning in organizations: (1) advanced digital systems (“smart machines”) and their ever-growing capacity for carrying out tasks and (2) collaboration of employees with these smart machines (hybrid activities and augmentation). In the context of digital transformation, hybrid activities (where humans complement smart machines and smart machines boost human capacities) become an important driver for organizational performance. We discuss fusion skills (as a prerequisite for successful hybrid activities) and augmentation strategies (developmental strategies by humans related to smart machines in the workplace) as key concepts for HRD professionals and their effort to contribute to the move toward a learning organization. Fusion skills refer to, for example, training smart machines for performance and acceptance; algorithmic testing, editing, and output interpretation; and managing the operations and performance of smart machines. Augmentation strategies can be differentiated into step in, step up, step aside, step forward, and step narrow. We provide results from empirical research among HRD professionals in German-speaking countries on their stance toward these augmentation strategies, and we conclude that HRD professionals need to (1) understand smart machines, fusion skills, and augmentation strategies as well as their implications at a personal level, (2) establish effective practices at the level of the HRD function that are oriented to fusion skills and augmentation strategies, and in this way (3) contribute to the move toward a learning organization.

Full textAbstract:
Steady state computations have traditionally been used for liquid pipeline hydraulic design. The hydraulic behavior of multiproduct pipelines is more complex than single-product lines because the throughput varies with time as the different batches move through the system. Designing a multiproduct pipeline involves hydraulic simulation to ensure that the system can meet a specified time-average throughput for the design batch line-up. To calculate the time-averaged throughput, the hydraulic simulation determines the total time it takes to ship the complete design batch cycle and the methodology must account for the time-varying throughput of the pipeline. Two basic methods available to accomplish this are: the fully-transient method, and the simpler succession-of-steady-state method. A fully-transient model would rigorously solve the time-dependent equations of energy, mass and momentum conservation to determine operating capacity. A succession-of-steady-state (SSS) model is one where batches are moved through the system in small volume increments, and the steady-state capacity is calculated at each step. Fully-transient type software models are powerful, but expensive, complex and usually require lengthy simulation run times. An SSS spreadsheet model would not be used to evaluate transient phenomena, but is adequate for determination of nominal pipeline capacities. This paper discusses the development of a trans-thermal, SSS spreadsheet based model that was created as a design tool to determine pipeline capacity and evaluate the impact of design alternatives or changes.

Full textAbstract:
Abstract Two-phase flow in hilly terrain pipelines can cause significant practical operating problems. When slugs flow in a hilly terrain pipeline that contains sections of different inclinations they undergo a change of length and slug flow characteristics as the slug move from section to section. In addition, slugs can be generated at low elbows, dissipate at top elbows and shrink or grow in length as they travel along the pipe. A mathematical model and a computer program was developed to simulate these phenomena. The model was based on the sink/source concept at the pipeline connections. A connection between two pipeline sections of different slopes was conveniently called elbow. An elbow accumulates liquid as a sink, and releases liquid as a source. The sink/source has a characteristic capacity of its own. This capacity is positive if the liquid can indeed be accumulated at the elbow or negative if the liquid is actually drained away from the elbow. This type of treatment effectively isolates the flow upstream from an elbow from that downstream, while still allowing flow interactions between two detailed pipeline sections. The hydrodynamic flow model was also used to calculate the film liquid holdup in horizontal and inclined pipelines. The model can successfully predict the liquid film holdup if the liquid film height is assumed to be uniform through the gas pocket. Many other models were used to calculate all the needed parameters to perform the sink/source model. The overall effect of a hill or terrain on slug flow depends on the operating flow rates and pipeline configurations. For special case of near constant slug frequency corresponding to moderately high superficial liquid and gas velocities, this effect was found to be small. The changes in the film characteristics between two adjacent pipeline sections were found to be mostly responsible for the pseudo-slug generation, slug growth and dissipation in the downstream pipeline sections. The film liquid holdup decreased with increasing pipe diameter. The unit slug length increased at the upstream inclined pipes and decreased at the downstream inclined pipes with increasing pipe diameter. The possibility of pseudo-slug generation was increased at large pipe diameters even at high sink capacities. At low sink capacities, no pseudo-slugs were generated at high superficial velocities. The slug flow characteristics was more effected by low superficial gas and liquid velocities, large pipe diameters and shallow pipeline inclinations.

Full textAbstract:
In widely used closed-loop drive scheme for capacitive vibratory microgyroscopes, additional capacitive interfaces for monitoring of the drive mode is avoidless. In addition, capacitive interfaces for tuning the resonance frequency of microgyroscopes is also necessary for closed-loop detection. Introducing these additional capacitive interfaces, the sense capacitances became much smaller, and the efficiency of the driving became lower. Correspondingly the sensitivity of the capacitive vibratory microgyroscopes decayed. This paper presents a universal and simple interface circuit without these additional capacitive interfaces. One single-ended bridge is formed by a pair of drive capacitors and sense capacitors. The vibrating mass, as the output of the bridge, is held at virtual ground by a charge integrator. Drive voltage combined with high-frequency carriers is applied to fixed node of the drive capacitors. High-frequency carriers with offset which are used as feedback force are applied to fixed node of the sense capacitors. Thus output of the integrator includes modulated driving, sensing mode signals and the drive voltage. Due to the high Q of the microgyroscopes, the carriers have no impact on the drive mode. And the frequency of the drive voltage is usually much lower than the carriers, so a low pass filter can be used to eliminate the influence of the drive voltage on the integrator. The two carriers have different frequencies, and the band pass filters can be used to separate the modulated driving and sensing mode signals. Using two capacitive vibratory microgyroscopes with different structures and capacitive interfaces, the experiments were respectively carried out. The results indicated that the 1/f noise was effectively reduced, (and) the couplings of the driving ()on sensing signal was eliminated. The circuit can resolve variations of input capacitance less than 1fF.

The world’s energy supplies will continue to be pressured as population grows and the standard of living rises in the developing world. A move by the rest of the world towards energy consumption rates on par with the United States is most probably unsustainable. An examination of population trends, current energy utilization rates, and estimated reserves shows that a major worldwide transition to renewable resources is necessary in the next one hundred years. This paper examines one possible scenario of how energy usage and renewable power generation must evolve in this time period. As the global standard of living increases, energy consumption in developing nations will begin to approach those of the developed world. A combination of energy conservation and efficiency improvements in developed nations will be needed to push the worldwide energy consumption to 200 million BTU per person per year. Fossil fuel resources will be exhausted or become prohibitively expensive, necessitating the development of renewable energy resources. At this projected steady state population and energy consumption, the required contribution of each type of renewable resource can be calculated. Comparing these numbers to the current renewable capacities illustrate the enormous effort that must be made in the next century.

The paper presented here focuses on the idea of interpreting the digital culture as an image of the material culture rather than a mere copy of it. First of all, we should ask ourselves what an image really is; it is in investigating its deep meaning, which is often devalued due to the enormous dissemination of void images, that we can overcome the superficial concept of the digital as a digitalised copy. The description of an archaeological artifact cannot prescind from its physical and material appearance, but has to go further towards its profound nature and meaning. Considering the so-called aura of archaeological and artistic objects as an engagement between the hic et nunc of the object and the hic et nunc of the observer it will be possible to go beyond in the comprehension of the agency of the objects. Moreover, it is necessary to consider technology as a way through which objects could reveal themselves in a process of ἀλήθεια and not just a tool with the only scope of showing itself and its capacities. Considering digital copies as images could yield compelling challenges: every archaeological object, at any scale from the very little to the very big, has its own lost Umwelt: a way of being entangled in the world in which it was created. Probably, no answer will be provided within this paper, but suggestions to move towards an ontology of digital objects and their relationship with virtual realm.

Full textAbstract:
Abstract CO2 geological storage (CCS)isconsidered as the most promising technique to reduce atmospheric CO2emissions. However, due to the density variation between the injected supercritical CO2 and the formation water,CO2 tends to move vertically toward the air. This vertical CO2 leakage can be prevented by four trapping mechanisms (i.e. structural trapping,capillary trapping, solubility trapping, and mineral trapping). The capacities of structural and residual trapping are highly affected by rock wettability. Clay wettability is one of the crucial parametersin evaluation of CO2 geo-sequestration. However, the literature data show that there are many uncertainties associated with experimental measurements. One of these uncertainties is the influenceof the effect of gas density on the clay mineral wettability. Thus, here, we compared the wettability of a clay mineral (i.e. illite) of three different gas densities scenarios (i.e. low (Helium), moderate (Nitrogen), and high (CO2) gas densities). To do so, we measured the advancing and receding contact angle (i.e. wettability) of illite for CO2/water, nitrogen/water, and Helium/water systems at a constant (333 K) and four different pressures (5, 10, 15, and 20 MPa). The brine composition used was 4 wt% NaCl, 4 wt% CaCl2, 1 wt% MgCl2 and 1 wt% KCl, for all gas density scenarios. The results indicate that gas density has a significant effect on the clay mineral wettability and that both advancing and receding contact angles increase with an increase in gas density. The results show that a higher density gas scenario has a higher contact angle of illite, measured at the same temperature and pressure. For instance, the advancing contact angle of illite at 333 K and 20 MPa was 65° for the CO2/water system, 53° for the nitrogen/water system, and 50° for Helium/water Helium/water system. Thus, we conclude that the gas density affects the Clay wettability measurement and that the higher gas density leads to a higher contact angle measurements (i.e. a more CO2-wet system) of the clay and thus reduces the estimated CO2 geo-sequestration capacity and containment security.

Studies have been performed to propose reliability based design criteria for the installation of pipelines in the Bay of Campeche, Mexico. This paper summarizes formulations that were used to characterize the important Ultimate Limit State capacities of the pipelines during the installation period (collapse, bending, tension, combined, and propagating buckling). A large database of laboratory and numerical analysis ‘tests’ (more than 2,000 results) to determine pipeline capacities was assembled to help evaluate the Biases (ratio of measured/predicted capacities) in the analytical methods used to determine pipeline capacities. Given the formulations, target reliabilities, and installation demand characterizations summarized in a companion paper (Part 1), installation design criteria were developed for both Working Stress Design and Load and Resistance Factor Design formats.

As the unequal impact of the COVID-19 pandemic continues, there is a need to robustly support vulnerable communities and bolster ‘community resilience.’ A community resilience approach means to work in partnership with communities and strengthen their capacities to mitigate the impact of the pandemic, including its social and economic fallout. However, this is not resilience which returns the status quo. This moment demands transformative change in which inequalities are tackled and socioeconomic conditions are improved. While a community resilience approach is relatively new to epidemic preparedness and response, it frames epidemic shocks more holistically and from the perspective of a whole system. While epidemic response often focuses on mitigating vulnerabilities, there is an opportunity to use a resilience framework to build existing capacities to manage health, social, psychosocial, and economic impacts of an epidemic. This makes a resilience approach more localised, adaptable, and sustainable in the long-term, which are key tenets of an epidemic response informed by social science.

As the unequal impact of the COVID-19 pandemic continues, there is a need to robustly support vulnerable communities and bolster ‘community resilience.’ A community resilience approach means to work in partnership with communities and strengthen their capacities to mitigate the impact of the pandemic, including its social and economic fallout. However, this is not resilience which returns the status quo. This moment demands transformative change in which inequalities are tackled and socioeconomic conditions are improved. While a community resilience approach is relatively new to epidemic preparedness and response, it frames epidemic shocks more holistically and from the perspective of a whole system. While epidemic response often focuses on mitigating vulnerabilities, there is an opportunity to use a resilience framework to build existing capacities to manage health, social, psychosocial, and economic impacts of an epidemic. This makes a resilience approach more localised, adaptable, and sustainable in the long-term, which are key tenets of an epidemic response informed by social science. This brief presents considerations for how health and humanitarian practitioners can support communities to respond to and recover from COVID-19 using a community resilience approach. This brief was developed for SSHAP by IDS (led by Megan Schmidt-Sane with Tabitha Hrynick) with Anthrologica (Eva Niederberger).

House, Sarah. Learning in the Sanitation and Hygiene Sector. Institute of Development Studies (IDS), July 2021. http://dx.doi.org/10.19088/slh.2021.004.
Full textAbstract:
This SLH Learning Paper summarises the key learning from a rapid topic exploration on 'Learning in the Sanitation and Hygiene Sector'. The study looked at how people in the WASH sector learn, the processes utilised and what works best, as well as the barriers and challenges to learning. It looks at learning from communities and peer-to-peer and how the learning gets translated into action at scale. How do you think we learn best? What barriers do you see and experience that make it more difficult for us to learn? And what steps should be taking to reduce the barriers and improve how to learn more effectively? This paper shares the lessons from sector and associated actors working in low- and middle-income contexts around the world and makes recommendation on how to strengthen learning and sharing processes, as well as building capacities and confidence for learning, with the ultimate aim of turning that learning into action at scale.

Vonk, Jaynie. Sustainable Water and Sanitation in Zambia: Impact evaluation of the 'Urban WASH' project. Oxfam GB, February 2021. http://dx.doi.org/10.21201/2021.7284.
Full textAbstract:
The ‘Urban WASH' project was implemented in George and Chawama compounds in Lusaka between July 2013 and June 2017 by Oxfam and Village Water Zambia. The project aimed to improve provision and sustainable management of WASH services by engaging citizens to hold duty bearers and service providers to account. Oxfam collaborated with local institutions on an array of activities, engaging stakeholders to create a conducive environment for service provision and improving capacities and practices. This Effectiveness Review evaluates the success of this project to increase the sustainability of water and sanitation systems and services. Using a quasi-experimental evaluation design, we assessed impact among households in the intervention communities and in a comparison community. We combined the household-level quantitative assessment with analysis of community-level qualitative Key Informant Interviews, carried out with relevant institutional representatives.

Sánchez-Páez, David A. Effects of income inequality on COVID-19 infections and deaths during the first wave of the pandemic: Evidence from European countries. Verlag der Österreichischen Akademie der Wissenschaften, August 2021. http://dx.doi.org/10.1553/populationyearbook2022.res1.1.
Full textAbstract:
Evidence from research on infectious diseases suggests that income inequality is related to higher rates of infection and death in disadvantaged population groups. Our objective is to examine whether there was an association between income inequality and the numbers of cases and deaths during the first wave of the COVID- 19 pandemic in European countries. We determined the duration of the first wave by first smoothing the number of daily cases, and then using a LOESS regression to fit the smoothed trend. Next, we estimated quasi-Poisson regressions. Results from the bivariate models suggest there was a moderate positive association between the Gini index values and the cumulated number of infections and deaths during the first wave, although the statistical significance of this association disappeared when controls were included. Results from multivariate models suggest that higher numbers of infections and deaths from COVID-19 were associated with countries having more essential workers, larger elderly populations and lower health care capacities.

Price, Roz. Access to Climate Finance by Women and Marginalised Groups in the Global South. Institute of Development Studies (IDS), May 2021. http://dx.doi.org/10.19088/k4d.2021.083.
Full textAbstract:
This paper examines the issue of management of climate finance in the Global South. It acknowledges the efforts made by the various stakeholders so far but seeks to advance a clarion call for a more inclusive and targeted approach in dealing with climate change. The authors highlight the limited role played by least developed countries and small island developing states in contributing to the conversation on climate change. The authors emphasize the need for enhancing the role of the most vulnerable countries, marginalized groups, and indigenous peoples in the management of climate change. This rapid review focusses on the access to the Green Climate Fund by local civil society organisations (CSOs), indigenous peoples, and women organizations within the Global South. The authors observe that there still exist barriers to climate finance by local actors in the Global South. The authors note the need for more significant engagement of all local actors and the need to devolve climate finance to the lowest level possible to the most vulnerable groups. Particularly, climate finance should take into consideration gender equality in any mitigation measures. The paper also highlights the benefits of engaging CSOs in the engagement of climate finance. The paper argues that local actors have the potential to deliver more targeted, context-relevant, and appropriate climate adaptation outcomes. This can be attributed to the growing movement for locally-led adaptation, a new paradigm where decisions over how, when, and where to adapt are led by communities and local actors. There is also a need to build capacities and strengthen institutions and organisations. Further, it is important to ensure transparency and equitable use and allocation of climate finance by all players.
